I spent the weekend surrounding my birthday backpacking in the Belly River region of the park. It was the most beautiful trip I've taken. The hiking was gorgeous, the trails well maintained, and the wildlife... abundant. Saw 3 black bears and 1 grizzly bear, and a plethora of other animals during our trip.
We spent the first night at Cosley Lake, and the second at the Elizabeth Lake Foot. Both gorgeous campgrounds with incredible scenery. As we hiked out, we were both looking forward to hot meals and showers, but sad to be leaving such a beautiful place.
